As the comments point out, getting up at 5:00 AM isn't exactly unique to CEOs. Neither is working until midnight. Although unless you are a CEO doing both at the same time is uncommon.
I'd do it for a year if they paid me a million bucks. Then I'd invest and live off that for the rest of my life.
We've lived off less than 50K/year before. If it meant that my reward for that one year of hyper stressful work was being able to play video games, write crappy stories, and putter around the garden for the rest of my life, I might do it.
